Table 3 lists the number of cycles taken to perform
some primitive operations in SPACE, and the resulting measured peak
performance for the PADMAVATI prototype. The reader is referred to
[Foster1976] for a detailed exposition of CAPP algorithms. All
these routines are executed conditionally, taking effect only in those
words where a user defined tag field in each word matches a user
defined tag value.

Table 3: Measured SPACE performance with 170496 words in PADMAVATI.

In the PADMAVATI prototype, execution speed is limited by the
transputer used to issue instructions. The performance of the existing
modules could be increased by nearly a factor of 8 by using a
dedicated microcontroller operating over a synchronous bus. In this
case, the peak performance of the array would be over
